We are leaders on Polish market in areas of broadcast sound, sound reinforcement, public address and communications systems. For designing purposes we are using specially designed software (WS CAD, AutoCAD, EASE 3.0). Each advanced project is preceded with computer simulation. Our staff is fully trained by our equipment suppliers. Our principle is to be professional, reliable and upright. In 2007 we inculcated quality management system, complying with ISO 9001:2000, certified by Decra. We are realizing principle of „from design to start up”. All these allows us to solve all problems concerning sound reinforcing in any object quickly, reliably and efficiently and be up to any challenge.
